• What is the cause and solution for SAP error message PQ660 - Unable to delete data ?

  The SAP error message PQ660, which states "Unable to delete data," typically occurs in the context of the SAP Production Planning (PP) module, particularly when dealing with production orders, planned orders, or other related data. This error can arise due to various reasons, and understanding the cause is essential for finding a solution.
  Causes of Error PQ660
  
  
  Data Locking: The data you are trying to delete may be locked by another user or process. SAP uses locking mechanisms to prevent data inconsistencies.
  
  
  Dependencies: The data you are attempting to delete may have dependencies or relationships with other data objects. For example, if a production order is linked to a material document or a sales order, it cannot be deleted until those dependencies are resolved.
  
  
  Authorization Issues: The user may not have the necessary authorizations to delete the data. SAP has strict authorization checks, and lacking the right permissions can lead to this error.
  
  
  Status of the Object: The object you are trying to delete may be in a status that does not allow deletion. For example, if a production order is already completed or closed, it may not be possible to delete it.
  
  
  Custom Logic or Enhancements: Custom code or enhancements in the SAP system may impose additional checks or restrictions on data deletion.
  
  
  Solutions to Error PQ660
  
  
  Check for Locks: Use transaction code SM12 to check for any locks on the data you are trying to delete. If you find locks, you may need to wait for the other user to release them or contact them to resolve the issue.
  
  
  Review Dependencies: Investigate any dependencies related to the data. Use transaction codes like CO03 (for production orders) or MD04 (for stock/requirements list) to check for linked documents. Resolve any dependencies before attempting to delete.
  
  
  Authorization Check: Ensure that the user has the necessary authorizations to delete the data. You can check this using transaction code SU53 to see if there are any authorization failures.
  
  
  Check Object Status: Verify the status of the object you are trying to delete. If it is in a status that does not allow deletion, you may need to change its status or take appropriate actions to allow deletion.
  
  
  Consult Custom Logic: If there are custom enhancements or logic in place, consult with your ABAP developers or SAP Basis team to understand if there are any additional checks that might be preventing deletion.
  
  
  Use Transaction Codes: Depending on the context, you may need to use specific transaction codes to delete the data properly. For example, use CO02 to change a production order and set it to a status that allows deletion.
